摘要
为了研究地铁列车的火灾安全疏散性能,利用Pyrosim火灾数值模拟软件,结合真实材料的物理化学参数,对地铁火灾的毒害气体和能见度分析,确定满载乘客的单节车厢应满足的最低转移时间。模拟地铁火灾真实的疏散场景,进行大规模疏散演练实验,探讨了人群实际转移时间和相关注意事项。利用Pathfinder疏散模拟软件,针对站台疏散和隧道疏散进行了比较分析。
In order to investigate the fire evacuation performance of subway train, the poisonous gas and visibili- ty in subway train in case of fire were analyzed firstly and the minimum transfer time was confirmed that a single carriage fully loaded with passengers shall satisfy by means of Pyrosim fire numerical simulation software and in combination with the physical and chemical parameters of real materials. Subsequently, the real evacuation scene in subway in case of fire is simulated and the large-scale evaluation experiments are carried out with a view to ex- plore the actual transfer time for crowd and the relevant points of attention. Finally, a comparative analysis between platform evacuation and tunnel evacuation is carried out through Pyrosim evacuation simulation software.
